As if Teen Mom 2 star Kailyn Lowry didn't have enough on her plate as a homeless 17-year-old with a child, drunk mother, no father, and a toxic relationship with her baby daddy, she just revealed that Isaac had some pretty serious health issues as an infant.

In her new book Pride Over Pity, the reality star wrote about her firstborn's seizures and how scary they were for her. She also sat down with OK! magazine to talk about the first time Isaac had a seizure.

"It [happened] in my lap. And that was the first time I had ever been in an ambulance in my life," Kailyn remembered. "And I just didn’t know where to go to for support because my mom has been in and out and then Jo was always at work, so I didn’t really know who I could count on to be there for me. When you have kids, they become your world. So I just felt like, was it something I did? Was it something that could have been prevented in the future? It was so hard."

Ugh, isn't that the worst part of motherhood? Not just your baby being sick, but the fear that you caused it or could have prevented it somehow?

The way Kail describes motherhood, how it just becomes your world, is spot on. I've also heard it described as watching a piece of your heart walk around outside of your body. Becoming a mother changes you in a way nothing else can. You're still you, but now you're a you that freaking made a person.

That's where the fears and insecurities come in -- if you made that teeny little person, and they get sick, does that mean you did something wrong?

Nope, not at all. Illness happens. Seizures happen. Kids get sick, and other than feeding and sheltering and supervising them, there's not a whole lot we can do to prevent it.

Thankfully Isaac grew out of his seizures and is now a healthy, rambunctious 4-year-old. Hopefully the biggest health concern Kail has these days for him is keeping the Band-Aids stocked for skinned knees.
